7875 + 5.9 + E85 + Megasquirt

I have the alum dual master cylinder with the larger bore. I think I bought it for a Dakota truck application but it’s the common one everyone uses. I don’t recall that bleeding those brakes was any trouble. I also have a proportioning valve for the rears.
Thank you, I’ll give that one a try. The instructions that came with the brakes say they need to be bled off the car, but the orientation puts the bleeder right at the top where it should be so I didn’t understand why. I’ve bled my system 10 times and the pedal still feels spongy until I pump them a bit. Also running a proportioning valve.
